Here is a ZHR graph of Southern delta Aquarids seen in 1984-1996:

126.784 10.9 1.3
126.938 10.5 1.7
127.385 7.1 1.3
127.508 7.4 1.0
127.756 9.2 1.3
128.014 9.6 1.4
128.253 7.9 1.1
128.568 9.3 1.5
128.805 6.2 0.7
128.970 5.5 0.6
The graph was derived from 748 records in the period ~July 24-Aug 1, F<2.5,
lm>5.0. No perception stuff and other sophisticated things were applied, just to
find the maximum. The records were divided into 0.25deg-bins in solar longitude,
the given sollong is the mean sollong of each bin (hence not equidistant).
A sollong=125.5 equals 1997, July 28, 12h30 UT. (All sollongs are epoch 2000.)
